AUTOMATIC SPRAYING APPARATUS.

Specification of Letters Patent.

Patented Sept. 24, 1912.

Application filed March 31, 1911. Serial No. 618,153.

To all whom it may concern:

Be it known that I, AARON J. TYLER, cit-izen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Automatic Spraying Apparatus, of which the following is a I specification.

This invention relates to apparatus for spraying insecticides, disinfectants and other liquid solutions, in which the spraying of the liquid solution is effected by compressed air or other fluid under pressure.

One object of the invention is to provide a spraying apparatus in which the parts will be so constructed and arranged that the pressure fluid will be admitted to the container and the liquid solution discharged therefrom through the same pipe.

A further object is to arrange the pump valve in the path of the liquid from the container so that when the liquid is discharged, the latter will form in efi ect a water seal for said valve.

A still further object of the invention is generally to improve this class of devices so as to increase their utility, durability and efficiency.

Further objects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

For a full understanding of the invention and the merits thereof, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a side elevation of a spraying apparatus constructed in accordance with my invention; Fig. 2 is a longitudinal sectional view of the same; Fig. 3 is a rear elevation; Fig. 4 is a longitudinal sectional View of the rear bearing plate or bracket, a plan view showing the bolts removed, being shown immediately above the saw c; Fig. 5 is a similar view of the front plate or bracket; Fig. 6 is a transverse sectional view, showing the manner of supporting the adjacent strap suspension clip in position on the rear plate or bracket; Fig. 7 is a similar View, showing the manner of attaching the other strap suspension clip to the front plate or bracket; ig. 8 shows a top plan view and silde elevation of each of the hose supporting 0 ips.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The improved spraying apparatus forming the subject matter of the present invention comprises a liquid container or tank 5, preferably cylindrical in shape, as shown, and formed of metal or other suitable material, said tankbeing provided with oppositely disposed heads 6 having their central portions concaved at 7 and their marginal edges retained in position on the tank, by

bending the side walls thereof inwardly, as indicated at 8.

Arranged within the container 5, is a substantially L-shaped discharge pipe 9, the horizontal arm of which is disposed in contact with or slightly above the bottom of the container and is provided with a series of perforations 10, through which air is l in the bend of the pipe to allow a portion of c the air to pass upwardly between the pipe and the mating head.

Arranged above the tank or container 5 and preferably disposed parallel therewith, is a pump cylinder 13, in which is mounted for reciprocation a rod 14, one end of which passes through a suitable gland 15 and terminates in an operating handle 16, while the other end of the rod is provided with a piston. The piston comprises an outer ring 17 and an inner ring 18 connected by spaced radiating ribs 19, the inner face of the outer ring 17 being provided with a curved seat 20 for the reception of a leather packing indicated at 21. The leather packing 21 is ar-,

ranged with the hair side thereof next to the inner wall of the cylinder 13, and is retained in position on the outer ring 17 by a disk 22, the latter constituting a seat for a flexible valve 23.

The cylinder 13 is provided with oppositely disposed heads or closures 24 and 25 having reduced threaded extensions 26, to which-are connected by suitable union nuts 27, angularly disposed nipples 28. The nipples 28 extend in opposite directions for attachment to flexible pipes 29 and 30, one of said pipes being provided with a spraying nozzle 31 and the other with a strainer 32 adapted to be inserted in a supply tank or other receptacle, when it is desired-to transfer the liquid solution from said supply tank to-the container 5. The head 24 is provided-with an inwardly extending flange 33 for engagement with a valve seat 34, there being a packing strip or washer 35 interposed between the valve seat and a sleeve on the adjacent end of the cylinder 13 for the purpose of preventing leakage between the parts. The'valve seat 34 is similar in construction to the valve seat 22 and mounted on said seat 34, is a flexible valve 36 by means of which the liquid in the container is prevented from being sucked upwardly and laterally into the cylinder 13 when the handle 16 is retracted.

The inner end of the rod 14 is preferably threaded for engagement with a clamping nut 37, which latter bears against the'valve seat 22 and serves to hold said valve seat and outer ring 17 in position on the piston rod.

Mounted on the upper portion of the container 5, near the rear end thereof, is a supporting bracket'38 having its lower face concaved at 39 toconformto the shape of the cylinder and its upper face pierced by spaced openings 40 for the reception of bolts or similar fastening devices 41, said bracket serving to receive and support a depending foot or standard-"42, preferably formed integral with the adjacent head 25 of the pump, as shown. The foot or standard 42 terminates in a base plate 43 adaptedto bear against the upper face of the bracket 38, there being openings 44 formed in the base plate 43 to permit the passage of the bolts 41 so that by rotating the clamping nuts 45, the base plate 43 will be securely clamped in position on the adj acent supporting bracket.

Arranged at the forward end of the tank or container 5, is a similar supporting. plate orbracket 46 having a socket '47 formed therein, whichlatter extends through thead jacent wall of the container 5 for 1 engage:

ment with a nipple 48 mounted on the upper arm of the discharge pipe 9.

The forward head 24 of the. pump cylinder is provided with .a retaining plate 48"- having a depending nipple 49 which fits withinthe socket47 and permits. the free.

discharge of liquid through the pipe 9, head 24 and hose section 29 to the spraying nozzle 31.

As a means for suspending the container from the shoulders of the operator, there are provided suitable clips 50 having loops 51 pivotally mounted thereon for attachmentto a suitable suspension strap, (not shown). The clips 50 are provided. with perforations to permit the passage of the adjacent bolts 41 so that when the nuts 45 are adjusted on said bolts, the lower faces of the nuts will bear against the clips and thus securely hold isaid clips in position on the adjacent sup- Eportingbrackets. The inner end of one of f the clips 50-is provided with a slot 52 adapted to receive a rib 53 formed on the foot or standard 42, while the inner end of the other clip 50 is concaved at 54 'for engagement with the exterior wall of the nipple 49, thus to assist in firmly anchoring said-clips on the supporting brackets.

The hose sections 29 and 30 are preferably retained in assembled position by suitable clips 55, each having its lower portion split at 56 so as to permit the clip to be clamped around the adjacent flexible hose section and ;its other end terminating in clamping fingers 57 adapted to embrace the mating hose section.

The spraying nozzle31 may be of any suitable construction and is provided with the usual shut off collar 58, although a turn- ,ing-plug or valve may be used instead for controlling the flow of liquid solution to the tip of the nozzle, if desired.

In operation, the valve 58 is moved to Qclosed position and the handle 16 reciprocated, so as to force air under pressure into ithecontainer 5, the operation of the pump gbeing continued until approximately fifteen lduced into said container.

pounds of compressed air has been intro- The stralner 32 ;is then introduced into the liquid supply Qtank and the handle of the pump again rel ciprocated so as to transfer the liquid soluition from the supply tank through the nip- ;ple 28, cylinder 13 and pipe 9 to the interior of the container 5. As the liquid solution is introduced into'the container 5, the air within the tank will be further compressed until the pressure thereof approximates fifty pounds to the square inch, which pressure, in actual practice, has been found sufficient to thoroughly spray the liquid solution. When pumping air into the tank,

the strainer 32 will, of course, be supported in elevated position by the adjacent clip 55. On the rearward stroke of the pump piston, the valve 36'will be moved to-closed position and a partial vacuum formed between said valve and piston head with the result that as. the:piston continues to travel in a rearward direction, the air at the rear of said piston will open thevalve 23 and passto the front thereof. On the forward stroke of the pump piston, the valve 86 will be moved to open position, so that the air in the cylinder 13 will be forced through the pipe 9 and perforations 10 into the tank, as before stated. It is obvious that the valves 36 and 23 will operate in a similar manner when transferring the liquid solution from the supply tank to the container 5.

It will here be noted that the valve 36 is disposed in the path of the liquid discharged through the pipe 9, so that said liquid coming in contact with the valve 36, will form in effect a water seal for the latter. It will also be noted that the construction of the pump is such that said pump may be used for introducing either air or liquid into the container 5, thus dispensing with a separate pump for this purpose.

By arranging the perforated pipe near the bottom of the liquid container 5, practieally all of the liquid solution in the tank may be discharged from the container without permitting the escape of an appreciable amount of air or without the necessity of recharging the container with air during the spraying operation. The mrforations 10 are also so disposed as to cause a uniform diffusion of air throughout the contents of the container and thus prevent the settling of the heavy particles of solution on the bottom of said container. lVhile the pump cylinder and its associated parts are preterably arranged on the exterior of the tank, it will of course be understood that said pump cylinder may be arranged within the container or tank without departing from the spirit of the invention. It will also be understood that the pump may be used for various other purposes, and for this reason, although described with great particularity, is not claimed specifically in the present application, it being my intention to file a separate application embodying the specific construction of the pump mechanism.
